OpenCV入門（0）——安裝，配置

     1.  下載Opencv，安裝

      2.  配置環境變量

               一、系統變量 Path：添加D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\bin

               二、用戶變量：添加opencv變量，值D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\bin變量值實際爲bin文件夾的路徑；

               說明：無論你係統是32位仍是64位，路徑目錄均選擇X86，由於編譯都是使用32位編譯；若是選用X64，則程序運行時候會出錯。

               重啓！

       3.  VS工程設置：

           1, 在項目->屬性對話框中，左側「配置」選擇「Debug」，而後「配置屬性」->VC++目錄，在右側設置「包含目錄」，新添加：

                D:\opencv\opencv-2.4.9\opencv\build\include

                D:\opencv\opencv-2.4.9\opencv\build\include\opencv

                D:\opencv\opencv-2.4.9\opencv\build\include\opencv2

           2, 在「庫目錄」，添加:

                D:\opencv\opencv-2.4.9\opencv\build\x86\vc12\lib

           3,【通用屬性】 ->【連接器】->【輸入】->【附加的依賴項】

                debug:
